Execute sudo command in ubuntu from java class

Question

I have a sh file which conatins a many sudo commands, say a script as below:

test.sh

#!/bin/sh
sudo apt-get install gedit
sudo date --set="2014/02/20 10:00"

When I execute the test.sh from terminal it works fine. Problem is when I try to execute this file from a java class. The script doesn't execute. I tried this:

Process proc = Runtime.getRuntime().exec("/bin/sh","/home/priyatam/test.sh");

Does anyone have an idea to execute this sudo command from java class? Please share.

Answer 1

well as the script will be outputting the prompt to the screen, it will be necessary to capture the processes inputstream

InputStream stdout = process.getInputStream ();

I would also recommend using

ProcessBuilder builder = new ProcessBuilder("/home/user/test.sh");
builder.redirectErrorStream(true);
Process process = builder.start();
